The Volkswagen Polo GTI can trace its roots back to the original hot Polo, the supercharged 1.3-litre 85 kW (115 PS) G40. It was sold in the United Kingdom between 1990 and 1994 in the form of the Mk2F Polo but was available during the late 1980s in limited numbers in Europe in the form of the Mk2 Polo GT G40.
Another common issue is camshaft timing chain tensioner failure, again in earlier generation 1 models. This was due to the design of the retaining element that after higher mileages and / or premature wear stopped the tensioner from holding the tension in the timing chain.

The crankshaft drives the camshaft (via a timing belt, timing chain or gears), which in turn actuates the intake and exhaust valves. [1] These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. [2] The most common devices to transfer the drive are toothed rubber belts, metal timing chains or a set of ...
The EA827 family of petrol engines was initially developed by Audi under Ludwig Kraus leadership and introduced in 1972 by the B1-series Audi 80, and went on to power many Volkswagen Group models, [5] with later derivatives of the engine still in production into the 2010s.
